DUPLEX WIND-MOTOR.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed September 17,` 1906. Serial No. 335,024.

To all wwm/ t Wray concern;

Be it kno`wn that I, ORLANDO KIRKHAM, a citizen of the United States,residing at Marshalltown, in the county of Marshall and State of Iowa,have invented a new and useful Duplex TWind-Motor, of which thefollowing is a specification.`

My object is to increase the power of a wind-motor; and my inventionconsists in mounting two'wind-wheels in juxtaposition and combiningmechanism therewith for collecting and transmitting power and motiontherefrom to extraneous machinery, as

hereinafter set forth,- pointed out inV my claims, and illustrated intheaccompanying drawings, in which- Figure 1 shows the top of a tower insection, a frame for supporting two wind-wheels, and power-transmittingmechanism rotatably mounted :in the frame and combinedas required forpractical operation. Fig. 2 is a side view that shows the twowind-wheels in position relative to each other as required to besimultaneously engaged by the wind and rotated in reverse directions, sothat each wheel will catch and deliver wind-power at the same time to arotatable crank-shaft and reciprocating rod for transmitting power to apump or other extraneous machine.

The numeral 10 designates the top of a tower, preferably cast-iron,fixed von posts 12, as shown, or in any suitable way. It has a centralopening large enough for a person to pass through and a circular groovein its top face in which are placed a plurality of balls as required tosup ort the frame rotatably mounted on the fixed top 1Q in ballbearings.

The circular base 13 of a rotatableframe has a circular groove in itsunder side to cover the balls in the groove in the top 10 and also has aconcentric circular groove in A circular rplate 14, having a circulargroove in its under side, is fitted and fixed to the top 10 to admit and'cover the balls in the groove in the top of the base 13 of therotatable frame, and the base 13 has vertical extensions 15, to whichare fixed uprights 167 as shown or in any suitable way, as `required forsupporting the two wind-wheels and the power collecting and transmittingmechanism. v

A shaft 17isfixed in the top ends of the uprights 16, and a vane 18 isfixed to the end of the shaft. VVind-wheels A and B are loosely mountedon the shaft 17 and have .Sprocket-wheels 19 fixed to their sides.

required to rotate in reverse ways relative to a wind-current and toeach other. A crank-shaft 2O is mounted on the uprights 16 of therotatable frame and sprocketwheels 21 fixed thereto inalinement with thelwheels 19 on the fixed shaft 17and connected therewith by'chains 22. Inorder to A transfer power from the wheel B, that rotates in reverse wayto the wheel A, the chain that connects it with the wheel 21 on therockshaft 20 is twisted, as shown in Fig. 1. A reciprocating rod 23 isconnected with the crank of the shaft 2O for transmitting the power fromthe wheels A and B jointly as required for advantageously operating apump or other machine.

In the practical operation of my invention the vane 18 will hold thewheels A andB square to changeable wind-currents, and the two wheelswill present theirbroad sides thereto and successively receive the sainewind-current and force as required to jointly operate the crank-shaft 20and reciprocating rod 23 for transmitting the force of the two wheelsand the increase of power for operating extraneous machinery.

Having thus set forth the purposes of my invention and the constructionand arrangement of all its parts, the practical operation and utilitythereof will be obvious.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a wind-motor, a rotatable frame composed of a rigid base, twouprights fixed to the base and a horizontal shaft fixed to the top endsof the uprights, means to support the rotatable frame and two windwheelsmounted loosely on the shaft and between the uprights to 'rotate inreverse ways.

2. In a wind-motor, a rotatable frame composed of a circular base, twouprights fixed to the edge of the circular base, a fixed horizontalshaft at the upper ends of the uprights, means to support the frame,twowind-wheels mounted loosely on the shaft to rotate in reverse waysand a vane Axed to one endof the shaft, to operate as set forth.

3'. In a wind-motor, a rotatable frame composed of a circular base, twouprights fixed on the base, a fixed horizontal shaft at the upper end ofthe uprights, means to support the rotatable base of the frame, twowind-wheels mounted loosely on the shaft to rotate in reverse ways, avane fixed to one lheir sails are inclined in reverse ways as IOO end ofthe shaft and means for jointly transmitting power from the two wheelsin one direetion from the wheels as they rotate in re- Verse directionsas set forth.

4. A duplex wind-motor comprising a xed frame support, a frame rotatablyconnected with the lixed frame, a shaft liXed to the top of therotatable frame in a horizontal position, two wind-wheels looselymounted on the shaft, sprocket-wheels iixed to the sides 4of thewind-wheels, a Vane fixed to one end of the fixed horizontal shaft, acrank-shaft mounted in the rotatable frame below the 1 two wind-wheels,sprocket-wheels fixed to the crank-shaft, chains on thesprooketreciprocating rod connected with the crank of the crank-shaft,to operate as set forth.
